dts: bindings: remove setting use-prop-label in st,stm32-ccm

We set 'use-prop-label' incorrectly in the st,stm32-ccm binding file.
This property is meant to generate names based on there being a label
property set in the node.  For st,stm32-ccm nodes we don't ever set
labels and the binding file doesn't specify a label.  So remove setting
'use-prop-label'.
